  2. 1. Toxicological studies of di-n-butyl phthalate (DBP) : Impact on the reproductive system and gut microbiota

    Author : Radwa Almamoun; Oskar Karlsson; Paula Pierozan; Harri Alenius; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dibutyl phthalate; Antiandrogen; Gut microbiota; Reproductive toxicity; Endocrine disrupting chemicals; Environmental contaminants; Phthalates; Plastics; 3D cell culture model; Exposome; Toxicology; Environmental Sciences; miljövetenskap;

    Abstract : The potential health impact of exposure to anthropogenic chemicals has raised major concerns worldwide. Phthalates are mainly used in the plastic industry and have been associated with adverse effects in humans. Di-n-butyl phthalate (DBP) is one of the dominant phthalates with a ubiquitous presence in the environment. READ MORE

  4. 2. Reproductive function in young Swedish men - Time trend, prenatal and adult exposure to smoking and phthalates

    Author : Jonatan Axelsson; Malmö Reproduktionsmedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Semen analysis; maternal exposure; paternal exposure; smoking; phthalate;

    Abstract : A decrease in male reproductive function, including sperm counts, during the second half of the 20th century, has been postulated. During this period, testicular cancer has increased several-fold. Environmental and lifestyle-related factors have been proposed as explanations for a possible negative trend in male reproductive function. READ MORE

  5. 3. Toxicogenomic responses in Daphnia magna

    Author : Asmerom Seyoum; Per-Erik Olsson; Ajay Pradhan; Joachim Sturve; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ERA; organic pollutants; toxicogenomic; phthalate; PFAS and DBE-DBCH;

    Abstract : Detection of various organic contaminants in the aquatic environment at low concentrations, has raised concerns for animal and human health. Structural similarities of these compounds to estrogens and ecdysones suggests that organic pollutants may interfere with hormonal system of aquatic organisms. READ MORE

  6. 4. Thermal Isomerization of Azobenzene Side Chain Copolymers

    Author : Viktoria Skeppstedt; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; free volume; thermal isomerization; positron annihilation lifetime spectroscopy; physical ageing; phthalate; methyl methacrylate polymer; azo polymers; plasticization;

    Abstract : Irradiation of azobenzene induces isomerization between its trans- and cis forms. By introduction of azobenzene chromophores in polymers, it is possible to optically control a variety of polymer properties. The isomerization of azobenzene can be used to influence conformational, optical or surface properties of the poly mer material. READ MORE

  7. 5. In vitro and in vivo studies on the toxicology of di-n-butyl phthalate (DBP) : Effects on reproductive, endocrine, and immune systems

    Author : Liselott Källsten; Oskar Karlsson; Paula Pierozan; Jonathan W. Martin; Jorma Toppari; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dibutyl phthalate; Endocrine disrupting chemicals; Male reproductive health; Phthalates; Immunotoxicity; Toxicology; Steroidogenesis; Environmental Sciences; miljövetenskap;

    Abstract : Chemical pollution is an increasing societal problem and has a major impact on human and environmental health. One important source of chemical pollution is plastic, which contains many different compounds with often largely unknown hazards. READ MORE
